I highly recommend using a grout cutting bit in a Dremel tool. Using a
grout saw would be home repair hell.

I haven't tried a grout saw, and the Dremel grout removal bit and
attachment worked well. Tedious, but does the job. I believe I used 3
bits for our shower walls, part way up. 3 walls about 4' wide, removed
grout about 5' up. Most important issue would be to make sure grout space
is wide enough for the bit or you might chip tile.

Not only that, but it can bust plenty of blades, which gets tedious AND
expensive. The thing is, you don't have to clear out ALL the grout. Yes
you can take more out with the Dremel, but if you only have to take out a
little, the saw should be fine.
